- B. 80.6 km/hr
- C. 82.2 km/hr
- D. 79.2 km/hr
- Correct Answer
- 79.2 km/hr
ExplanationLength of train = 264 m
Time taken to cross the pole = 12 sec
Speed of the train, in m/sec = Length of the train/ Time taken to cross the pole
Therefore, speed in m/sec= (264 / 12) m/sec = 22 m /sec
Calculating speed in km/ hour = (22 m/sec ) x 18/5 = 396/5 km/hr = 79.2 km/ hour - 1. Find out the wrong number in the given sequence of numbers. 36, 54, 18, 27, 9, 18.5, 4.5
